Yep, got one myself; and unfortunately, Windows decided it was going to add this drive to the list of drives to defrag each week. Luckily, I caught this not too long after it was going on and stopped it but, it hurt performance. I was forced to do a secure erase on the drive to regain the factory performance.
OCZ SandForce drives have that terrible reputation and recently OCZ has adopted a new controller for their drives which seems to be much more stable but, much slower.
